To all whom it may concern:

Be it known that l, FnnnnnioK W. LIN- AKER, subject of the King ofEngland, residing at Dubois, in the county of Clearfield. and State ofPennsylvania, have invented certain new and usefullmprovements inFuel-Economizer Soot- Clea ers, of which the following is aspecification.-

This invention relates to improvements in fuel economizer soot cleanersand has for its vprimary object to provide in an economizer, a cleaningfluid distributing pipe or pipes for directing a cleaning fluid,preferably steam,upon the exterior surfaces of the tubes of theeconomizer whereby to effec-' tually free the latter of soot..

A further object of the invention is to provide in an economizer, afluid distribut ing pipe or pipes so constructed and arranged as todischarge the cleaning fluid be tween the rows of tubes of theeconomizer in streams along lines or paths radial to the I axis or axesof the distributing pipe or ipes.

A still further object isto provide in an economizer, a soot cleaningmeans in the form of a fluid-distributing pipe or pipes adapted todischarge cleaning fluid in jets or streams among and between theeconomizer tubes, and capable of oscillatory movement whereby to causesaid distributing pipe or pipes to vary the angularity or obliquity ofthe streams of cleaning fi-uid, thereby adapting the latter to cover awide radial area andto thus effect the removal of accumulated soot fromall of the rows of the economizer tubes.

Fuel economizers, as is well known, are utilized for the purpose ofheating water preliminary to its introduction into the boiler, and forthis purpose use is made of the waste gases and other products ofcombustion, the economizer being generally 10- cated in the path oftravel of such production, leading from the boiler or boilers to thechimney or stack, the economizers comprising a plurality of spacedvertically-ex-," tending tubes, the upper and lower ends of which areconnected by headers to provide a circulation of water therethrough. Asthe tubes are located in the path of travel of the products ofcombustion, the outer surfaces of the tubes quickly collect sootparticles carried by such products, destroying the maximum application,of heat to the tubes. Tube cleaners. which travel vertically over theouter-surfaces of the tubes have heretofore generally been employed for,removing such soot particles and scale as may collect on the tubes,these vcleaners acting in a manner similar to a scraper. Difficulty hasbeen 7 encountered in the use of cleaners of this pipes for a cleaningfluid, capableof being operated at any timewithout closing down theoperation of the furnace or the economizer, and which in operation inaddition to efl'ectually cleaning the economizer tubes of soot, aid thenatural draft in carrying off the removed particles, and enabling me atall times to procure a maximum amount of service from the economizer.

The nature of the invention will be readily understood as the same ishereinafter disclosed, and the said invention consists in the improvedconstruction, combination and arrangement of parts, hereinafter fullydescribed. illustrated in the accompanying drawings, and particularlypointed out in M the appended claim.

In the drawings, in which similar reference characters indicate similarparts in each of the views: Figure 1 is a plan View partly broken awayof an economizer of the -well known Green type, with a soot cleaner inaccordance with my invention applied thereto. Fig. 2 is a side elevationof the same partly broken away, and Fig. 3 is a detail side elevation ofa modified means for operating the distributing pipe. y

A fuel economizer of the Green type comprises a casing or setting 1which incloses the vertically-disposed economizer tubes 2 connected inthe usual manner at the upper and lower ends by headers 3. The tubes2 inthis type of an economizer are in parallel rows, and. in ordertoefi'ectually remove the accumulated soot from the tubes, it isdesirrows of tubes 2 at substantially right angles to the axis or axesof the distributing pipe or pipes that is arranged among the .tubes forcleaning purposes.

.- In thehere chosen illustration of my invention, I have shown aplurality of distributing pipes 4, these pipes being j ournaled in theopposite side walls of the setting or casing 1. Obviously, but a singlepipe, or as many of the pipes'as desired may be arranged, according tothe size of the economizer, in" which the cleaner is arranged.

Whether there be one or more pipes, each pipe is closed at its innerend, its outer end being in communication with a branch pipe 6connectedlwith a supply pipe 7, which latter is provided with the usualshut-off,.drain valve, etc. Each'branch pipe 6 is also provided with ashut-off valve 6'. Each pipe 4 is provided with spaced nozzles 8so-tlisposed with relation to the axis of the'pipe', that the cleaningagent is directed in jets or streams along paths or lines between therows of tubes 2 at substantially right angles to the pipe or pipes toremove accumulations of soot from the outer surfaces of the tubes,

these paths ,or lines upon' which the jets or streams of the cleaningagent are pro ected,

being clearly illustrated in Fig. 1 of the drawings. 'In order that thepipe or pipes 4 may be oscillated or partially rotated, the outer endsof these pipes connect by means of a swivel joint 9 With the branch pipe6, suitable means being provided for operating the pipe or pipes 4. Thismeans may be a hand wheel or handle 9' as in Fig. 3 on each pipe 4, orit may bea sprocket wheel 10 .upon each pipe 4, over which passes asprocket chain 11.

The operation of the means above described willbe readily understood. Acleaning fluid, preferably steam, being introduced into the distributingpipe through the connection shown, or other suitable supply and feedconnections, will be discharged through the nozzles 8 and projected injets or streams along parallel lines or paths between. the

several'circulating tubes of the economizer.

The oscillating movement of the pipe or pipes varies the radial paths ofthe streams of fluid issuing from the discharge nozzles, insuring'athorough cleaning of the water circulating tubes of the economizerthroughout their length, suchwide diffusion of the cleaning fluidpermitting it to permeate all of the spaces between the water tubes andany surface withln the economizer casing or' setting wheresoot may findlodgment.

While other means for oscillating the distributing pipe may be employed,I have found the simple hand-operated means herein shown and describedadmirably adapted for effecting the movement of the pipe or pipes, andas this mechanism is located entirely outside the casing or setting, itmay be operated conveniently and easily, and applied to, repaired,orremoved from the pipe andscope of the invention as claimed.

lVhat I claim as new is The combination with a fuel-economizer systemhaving parallel rows of vertical water-circulating tubes and located inthe path of travel of the products of combustion, and a settinginclosing said tubes, of a fluid d15- tributing pipe journaled inopposite walls of the setting and disposed between two ad 'jacent rowsof the tubes of the economizer and provided with discharge nozzles so(lisposed with relation to the pipe as to discharge a cleaning'agentbetween the rows of tubes in. jets or streams on, parallel lines orpaths at right angles to the axis of the pipe,

riorly of the economizer setting for rotating said fluid distributingpipe.

In testimony whereof I aflix my signature in presence of two witnesses.
